  - 4 KB of internal ROM (program memory)
- **I/O Ports**: 32 I/O lines (four 8-bit ports)
- **Timers/Counters**: Two 16-bit timers/counters
- **Serial Port**: One full-duplex UART (Universal Asynchronous Receiver/Transmitter)
- **Interrupts**: Five interrupt sources with two priority levels
- **Power Consumption**: Low power consumption due to CMOS technology
- **Operating Voltage**: Typically 5V
- **Package**: Available in various package types, including DIP (Dual In-line Package) and PLCC (Plastic Leaded Chip Carrier)
